Mine is automated message handling in iOS. Specifically I volunteer for a group that uses SMS with embedded links for the volunteers to tap to check in and out of a job. Frequently these links are truncated or divided in a way that makes their URL structure invalid. This happens all the time due to the difference in message length and how iOS handles longer messages. I know this boils down to an SMS character limit kludge, but our Android users do not experience this. The message comes as one block or "bubble" but the iOS users see multiple bubbles that are frequently out of order.
